Hi there hny4jc, I have spent an hour looking for the information you require and came up with nothing.

I see you have also posted in the official frogger area of the Konami support forum, I think that this is your best chance of getting an answer to your question.

When you do find out, please let us know, as it will help other gamers with the same problem as you in the future.

Best of luck in your quest !

Jim
